View in HD at . iPadOS (iOS 13) refines multitasking so it works better than ever. You can bring up two apps at the same time with Split View, or float a window over a full screen all with Slide Over. You can pile up Slide Over windows and flip through them too. Apps can interact with each other through dragging and dropping. There is a lot of different ways to use multitasking so it is best to practice a little before you need it.
